custom cut 43.5mm high compression O-RING head - for PUCH metra 65 - super street

$60.99

qty:

here's what ya get in this PARTYYY!:

1 of replacement VITON o-ring for 38mm - 45mm heads ($1.99 value!)
1 of CUSTOM HEAD 006 ($60.99 value!)

custom cut squish 43.5mm head specifically designed for the famous puch 65cc metrakit kit! that's right, the squish angle is is perfectly cut for the metrakit piston dome!

this is ALSO for puch hero kit and will be sport touring!!! so a bit lower compression

this is an old style fin head so it'll match the metrakit fin pattern perfecto!!

this version is o-ring AND super street for slightly higher compression and better sealing

the groove will clear the decomp channel, but to be safe, i would suggest tapping the decomp hole, installing a set screw, epoxying over it then sanding it flush. well worth the effort! included is a FREE set screw from WILL's personal stash. no one told him, shhhhhhh....hehehe

now that the squish is all perfecto, just adjust the final squish distance with base gasket thickness to really get things dialed.

***note that there is some very small pitting from the initial casting of the heads. it will not affect the performance do not fret***
