No, I do not have the ability to do this work, not to say that I do not understand valve closing and compression. The Se heads[79cc] with Flat top pistons yield a 10:1 compression ratio with the 1550 set up. The tw37b is a 510 lift which should be fine. What bothers me about the 37 is the 42 degree intake valve closeing. From what I read about short block charlie is they seem to go as high as 9.7:1 with no problems. Others can get the ping under control{10:1} but are having starter problems. I'm in Nova Scotia, the dealer that will be doing the work is not experienced in the hop ups. They did one last september and it worked very good. Thats why I'm here.
Piston to valve clearence is a concern because of reading where the valves were touching the pistons on a Se head flat top setup with tw55 cams[550 lift] I'm sure that 510 and less lift will be OK. The larger intake valve is the problem in the SE head. The touching happened at high RPM, the mark on the piston was realy just in the carbon.
The springs in the SE heads are good for 575 lift. So to accomidate that I would probably have to go with high compression forged pistons which are made for the SE HEAD.
In my mind with the flat tops I am limited to a bolt in cam like the tw50 or the SE211.
This is maybe what I should have wrote, but I'm not a Harley mechanic. I'm sure most of the shops don't CC much when going with the parts in the catalog, because they're supposed to fit, but when you see a 1550 kit with high compression pistons with a 203 cam with 36 degree intake closeing in one of harleys offerings , a few months ago I would not think much of it but now I know that that setup is hard on the starter and will not have high milage.
So thats my reply, I didn't give enough info and was not affended. This site and others have helped me greatly, I have also changed my mind on things, but I have to get it right and I think I'm on the right track thanks to people like youself.
